We now consider two natural saddle points, i.e. domain wall configurations for the Ising problem that arose in computing the \((m,n)\) -Rényi reflected entropy. These saddles are the tensor network analogs of the saddle points that were considered in Ref. [1]} and used to prove the correspondence in eq:srequals2ew. These were also interpreted as arising from the gluing construction of Refs. [2]}, [3]}, which has a natural analog in the tensor network case [4]}. This was one of several methods suggested for proving the correspondence in Ref. [1]}. The other method is studying the modular flowed correlators, which doesn't obviously extend to the tensor network case. In particular, these saddles are analogs of the LM saddles [6]} used to compute Rényi entropies in AdS/CFT.
